The IBM EXP810 expansion enclosure allows you to add up to 16 3.5" disk modules to your DS4300 (Turbo Online), DS4700 and DS5000 series storage servers. Disks may either be Fibre Channel or SATA E-DDMs (Enhanced Disk Drive Modules). SATA disk modules require a SATA-FC Interposer Card and can be intermixed with Fibre drives in the same enclosure with appropriate FC-SATA intermix licenses.
Please note that the EXP810 is a 4Gbps capable enclosure. A switch on the front of the EXP810 can force the EXP810 to operate on 2Gbps FC loops with older EXP710 arrays or use older 2Gbps FC disk drives. DO NOT install a 2Gbps FC disk module into a 4Gbps loop. ***ALL 10K RPM FC disk modules operate at 2Gbps. Most 15K FC disk modules are 4Gbps***
